Music dating back to the 13th century will be played out across Madrid from next month.
For a festival that's been around for 25 years, don't expect the line up to be outdated. There are 48 premieres on show, including national acts Trío Arbós and el Cuarteto Ercolani.
If you're on a budget, this festival gets even better. Most of the performances are free and for the ones that aren't, they won't break the budget. The cheapest ticket starts at €3, with the most expensive reaching €18.
